Contact Angle Goniometers

ramé-hart precision contact angle goniometers are backed by nearly 50 years of experience and reputation. ramé-hart was the first company in the world to manufacture a contact angle goniometer based on the NRL design of Dr. William Zisman. Today nearly five of decades of experience are bundled in each contact angle goniometer. ramé-hart only makes surface science tools for measuring contact angle and surface tension. That is our sole focus. Our machinists and instrument technicians hand build and assemble each unit to rigid specifications. No goniometer system will ship from our facility until it has been thoroughly tested and calibrated and every component is in proper working order. ramé-hart is the world-wide leader in surface science instruments and contact angle goniometers.

Our line of contact angle goniometer systems include:

• Model 190 Contact Angle Goniometer

• Model 200 Standard Goniometer with Surface Energy

• Model 300 Advanced Goniometer with Surface Energy and Surface Tension

• Model 400 Goniometer with Wafer Support

Note that all current goniometer models ship with a microsyringe fixture (p/n 100-10) and microsyringe assembly (p/n 100-10-20) for manual dispensing. A wide variety of needles are available. See our chart here: www.ramehart.com/pdf/needles.pdf. The optional software-driven Automated Dispensing System is supported on Models 200 and up.

In surface science, an instrument called a contact angle goniometer is used to measure static contact angle, advancing and receding contact angle, and in some cases, surface energy. The root goni refers to "angle" while meter refers to measuring device. Thus a goniometer is a measuring device for angles. While the term has been used to describe a tool used by physical therapists and also for measuring other types of angles, the traditional and more prominent use of the word "goniometer" has been to describe a contact angle meter.
